JAMES MOORE, OF ERGINETH, IRELAND.

Letters Patent N 101,645, dated April 5, 1870.

IMPROVEMENT IN FIRE-PLACES.

The Schedule referred to in these Letters Patent and making part of thesame vention applied thereto.

Figure 2 is a top or plan thereof.

Figure 3 is acentral vertical section.

Figure 4 is a central horizontal section in line ai a', iig. 3.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists in heating air by admitting it in a fresh statebelow the tire-chamber into a receiving-chamber and one or more tubestherein, in connection with one or moretubes in the tire-chambercommunicating with the receiving-chamber, so that the `air 'from theseveral points may be united in a heated condition and discharged.

In the drawings- A represents the tire-plate, and B B, the side plates,and E, the rear plate, which are constructed and arranged to form ahot-air chamber, D.

The rear plate E may be dispensed with, and in lieu thereof 1 may employslate or brick, and extend it from the ange N at the top of the chamberD to the brickwork around the tire-place, and coat such brick or slateroof with mort-ar or other cement, to prevent the escapeof hot air intothe chimney;

F represents a tube, which extends into the chamber D, and communicateswith one or more tubes, G, which are arranged within thecombustion-chamber K.

The ends of the tube pass through the side pieces B, and communicatewith the chamber I).

It will be seen that the air is admitted into the chamber D- and thepipe F beneath the plate P at space C.

Such air as ontcrs pipe F passes into the tube G, where it is heated,and thence into the chamber D.

The air that enters the chamber D from below is heated in its upwardpassage by contact with the plates A B, which are naturally heated bythe tire in the grate.

The hot air in the chamber D is dischargedinto the room at thc points Ior H, or other suitable locali. ties.

There is a constant current of air from the entrance into the chamber D`to its exit therefrom. It takes the cold air from the room or apartment,and dscharges it again in a heated state.

O represents a removable regulator or fender, which is to be placedacross thc face-plate in front of the tire-chamber K, andextending'suiciently high to cover the lower part of said tire-chamber.

M represents flanges, which secure the tire and side plates to theface-plate, and prevent thc escape of' gases int-o the hot-air chamber.

The pipes F and G maybe differently arranged, and multiplied, asdesirable; but it is intended that they assist in heating the air, whichit will be seen is heated by two operations, namely, such as passesdirectly into the chamber D from the space O, and comes in contact withthe heated platesl A B, and such as enters into the chamber throughpipes F G.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The receiving-chamber, and one or more tubes therein, in connectionwith one or more tubes in the fire-chamber communicating with thereceiving-chamber, so that the air from the. several points may heunited in a heated condition and discharged.

2. The vertical tube or tubes F, arranged wit-hin the air-chamber D,substantially as and for the purpose described.
